Don't have a Winder, but several Spinners. One from smoktek before they started the new name.
On them, the button light, after some initial flashing, stays on for a while when first connected to the charger, and my chargers will periodically blink red / green / red as the battery approaches full charge.
Thanks for the info! My Twists and even my mod batteries do that as well as they are close to getting full. However, this is happening as soon as I connect it and I definitely vaped that thing down to nothing as I used it heavily starting from early yesterday afternoon through last night and an hour or more this morning before it flashed the signal that the battery was drained. I've just never seen the power button light on the battery itself stay lit steadily while on a charger before and was worried that the charger and batter were not compatible with each other and some type of weird short or charge back was going on.
I know very little if close to nothing about circuitry and internal components so quickly unplugged it until I got some feedback on the matter. LOL The description on the website I bought it from said it worked with a standard Ego charger and that is what I had it hooked up to so I will try it again and see if the power button light on the battery doesn't go back off again if I wait a bit longer. I do like the battery very much and it seems to feel as if it has a bit more "oomph" than a Twist. Not as much as any of my larger mods but a difference I can tell nonetheless.
Also I so appreciate the easy to read numbers although I think I will take the advice of another poster here and find some red nail polish to make it more noticeable. It seems that my battery only received a partial red dot as it is very tiny, almost impossible to see except under bright light and looking closely. At first when I was checking it out after opening the mailing envelope I didn't think it had one at all! LOL So far this small and easily fixable issue seems to be the only problem I've encountered with it thus far. (well except for the panic attack it gave me when I tried to charge it earlier LOL)
Goodness knows I have enough broken Ego's put away, including a Twist who's button got jammed after being dropped off my lap and getting stepped on yesterday. It was very fixable until I attempted to do it myself and ended up destroying the button completely. Should have checked this forum first. First thing I see is a sticky addressing this exact issue. Sigh.....
Oh well, some modder somewhere might be interested in all of my broken devices for parts. I have 2 VV Grippers (3 actually but somehow got one of them working again the other day) one of which simply refuses to acknowledge any carto or tank any longer and stubbornly reports back either 0.0 or 9.9 and the other is in a bit worse shape after I tightened an Ego adaptor into it too much and then breaking it loose with needle nosed pliers caused it's early demise. The sunken threading piece broke loose from the case or circuit board or whatever it is attached to consequently disconnecting either one or more internal wires or other type connection (I'm assuming as it wouldn't even turn on after that LOL), then my hubby finished it off by opening it up to see if he could fix it (he doesn't vape nor knows anything about these devices).
I also have one of the first Ego VV batteries that offered 3 whole settings (color coded with red and blue lights), which BTW still works, or would if I owned and knew how to use a soldering iron (I can press the internal button on the circuit board and it still comes on and lights up, I long ago accidently pulled too hard on a carto that I thought was completely unscrewed but wasn't and pulled the cap piece with the threading right off. Wires popped off that piece but everything looks intact.
I also have an E-Vic with a dead control head.... NOT happy about THAT. A lot of money for 5 weeks of usage and considering I own many other devices it really didn't get used that much during that time! I need to hunt for a thread on that too, maybe it's an easy fix? The screen did a lot of flickering, weakly lighting up, and just plain refusing to come on for almost two weeks before it just quit coming on at all. Not even when plugged in and charging,which right before it died for good was the only way to get the control head to acknowledge the 5 button click. Ruled out a faulty battery by buying a replacement first and getting the same results with both batteries. I believe the hardware was faulty from the beginning because the software never was able to "see" the device even though when I plugged it into my USB port my computer made the sound effect when a USB device is plugged in and the control head would say "Uploading....charging" every time.
I did find it as cheap as $58 for a replacement but bought a $12 Ego Mod control head last week for it and that was a huge mistake. I am too used to VV at this point to go back to a one setting battery. I tried several tank set ups on it before putting it away in a drawer in disgust. Hence the purchase of the Winder.
